Actually they don't. No military in the world, AFAIK, issues semiautomatic versions of those weapons. The AWB did not affect the select fire versions which militaries *do* issue and use.
Unless the new and worse AWB, HR 1022, passes and is signed by the President, the Court will never get a look at the original AWB, which expired almost 3 years ago and was not renewed.
Here you are, arguing that Miller's homemade, sawed-off shotgun has military use, yet a factory-produced, semi-auto version of the M-16 doesn't.
You're credibility on this issue just went down the toilet.
